Smart Cursor Hints Disappear

Kenneth,

This sounds like a memory problem. Please call for direct technical support. This could also be a preference corruption issue, but I am leaning more towards memory.

If you are on a Mac, check your memory allocations.

On either Mac or Pc, please do not run other programs in the background that will usurp the memory from VectorWorks.

Thanks for the reply.

I'm on the Mac with 272MB physical RAM, 60MB allocated to VW8.5.2. My work requires other applications, so I use an Applescript to launch a handful of them each morning, with VW getting the first block.

What allocation sizes do you recommend?

I presume this is NOT a memory issue after all. Can anybody confirm that with higher (or lower) memory allocation that this problem goes away?

Again, the problem occurs when two or more documents are open. The smart cursor hints disappear in the other document when a 2D/3D symbol is edited. Opening and closing is the workaround. Seems like an application bug.

Kenneth,

As I said before, other programs can usurp the memory that VectorWorks requires. This very much sounds like a memory issue, as we here in Tech Support have found that to be the case of such instances hundreds of times. You have more than one document open, more than one program running when this occurs.

You have 60mb allocated to VW, but what is the minimum and the prefferred? Set your minimum to the suggested size, set the Preferred 40-50 mb above that. The difference is how much memory is available for the program to use. If you have both your preferred and minimum set to the same, there is no room for other files to work. If you have the minimum below the suggested, then the files will use the minimum first and may run out of memory. Check how much memory each file is using by utilizing the "About VectorWorks" function.

If the minimum and preferred are not locked then if VectorWorks does not use it immediately then other programs will take it. Remember, not only is VectorWorks and other programs you run using up memory, but so is your O/S, which takes around 30mb when you start up. Also, do you have virtual memory on or off? 3D objects like virtual memory. If it is off then you are allowing yourself less system resources.

Also, if you have rendered objects in your drawing and retain mode (preferences), QuickDraw3D is using RAM for that, adding to the amount required by your O/S. Also, each time you use RenderWorks (if you are) the memory is being held, so after 4 or 5 Renders with all the files and programs you have open you could easily run out of memory, even if nothing is currently rendered.

Again, call technical support and we will be glad to walk you through this process.

Thank you for the detailed reply.

Upon further testing, it seems memory is an issue after all. It occurs, however, only when I use my master drawing of symbols, which is 1.7MB in Finder. In the "about Vectorworks..." window, it reveals data as shown below. Is this file too big? My test is with VW8.5.2 with 15MB min, 60MB preferred, nothing rendered in QD3D, no Renderworks, and nothing else running. Screen shots below.

I do not understand how this particular drawing can reach VW's limit on memory use?

I used to run MiniCad for days at a time and not need to restart. Now I find that if I leave VW running overnight I get memory errors the followig day. So if there is a memory "leak" why can't it be plugged or failing that how about a ram purge feature?

After having read this exchange with interest (corruption problems) I took the advice of Brian and set the minimum to 12288 assuggested and the preferred to 64M and locked it.

Going back later to check I found the preferred had reverted to 24M by itself!

I did it again, and the same thing happened.

PowerbookG3, OS 9.0.4, VW 8.5.2, 192Mb, virtual memory on.

Am I missing something here???
